.To aZZ whom it may concern:

Be it known that I, WARREN WEBSTER, a cltizen of the United States,residing at Merchantville, county of Camden, and State of New Jersey,have invented a'new and useful Improvement in Apparatus for CondensingSteam, which improvement is fully set forth in the followingspecification and accompanying drawings.

My invention relates to an improvement in an apparatus for condensingsteam, as hereinafter described and consists in adapting such apparatusto eect condensation by vdirectlng the steam against or around one ormore pipes or other passages into which air 1s admitted, thus reducingthe temperature of sald pipes or passages by the action of such air.

Figure 1 represents a top or plan view of an apparatus for condensingsteam embodylng my invention, the draft producer being omitted from saidfigure. Fig. 2 representsA a vertical section of the apparatus.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings: A designates an exhaust head formed of thetubes B, a suryrounding shell or jacket C, a chamber D which is incommunication with the air or passage tubes B at the top thereof, thesteamsupply pipe E, which enters said jacket C,

the latter being open at top and closed at bot-Y tom, excepting at theplace of connection with the pipe E, and the discharge pipe J.

The tubes B are open at top and bottom, and connected with the sheets Fand G` respectively, the sheet F closing the bottom of the chamber D,while the top of the latter is left open.

Above the chamber Dis supported a hood H, which forms a draft-producer,as will be hereinafter more fully described.

The operation. is as follows:-Air enters the tubes B, and passes throughthe same, and steam is directed into the jacket C and circulates freelyaround said tubes, whereby owing to the reduced temperature of thelatter, the steam will be condensed, and the water of condensation maybe directed from the jacket by means of the spout or drip pipe J, to theplace of collection or discharge. Should the natural current of air inthe tubes B be thus increase the efciency of the apparatus l inproportion to the low temperature maintained in the air passages, itbeing noticed that the shell C is exposed to the atmosphere, whereby itstemperature may be reduced, and it may also be subjected toa blast ofcold air directed against the same so as to still further reduce itstemperature.

Some of the steam in the jacket C may retain sufficient life to escapetherefrom, this tbeing permitted at the open top of said jacket, asindicated by the arrows in Fig. 2.

It is obvious that the pipes B may be placed in other than verticalpositions if desired, and that other changes may be made withinY thescope of my invention, which may suggest themselves to those skilled inthe art.

It will be noticed that the air passages or tubes B are of less diameterthan the Vsteam supply pipe E, thus causing effective condensation ofthe steam in the jacket C. Y Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

l. In an apparatus for condensing steam,a series of pipes, tube sheetstherefor an air chamber in communication with the ends of said pipes, ashell having a space between one end thereof, and an adjacent tube sheetinclosing said pipes thereby forming a chamber, a steam inlet pipeleading into said chamber and a drain pipe leading therefrom, and adraft producer connected with said air chamber, said parts beingcombined substantially as described.

2. A steam condensing apparatus consisting of a series of pipes, tubesheets therefor a jacket surrounding said pipes forming a chamber havingone end closed, a steam pipe leading into said chamber, and a drain pipeleading therefrom, an air chamber in communication with the open ends ofsaid series of pipes, a hood forming a draft producer connected withsaid air chamber, said jacket supported above said tubes, a drain pipe,I0 chamber having an outlet between its Wall means for admitting steamto said chamber, and the wall of the air chamber, said parts and meansfor creating a draft through said being combined substantially asdescribed. pipes, the above parts being combined sub- 5 3.
